Colima, Mexico :

A pillar of ash shot 10,000 feet into the sky in a violent explosion of the Colima volcano in south-central Mexico. The event was captured on a web camera installed by scientists to monitor the active volcano in the Jalisco province.
The awe-inspiring timelapse footage shows the volcano as it burst last Friday. The mountain is still erupting intermittent explosions varying from 3,000ft to 9,800ft in height.

Footage from the webcam, installed across from the mountain to catch volcanic activity, is being analyzed by a specialized team at the University of Colima.
As Mt. Colima is one of the most active volcanoes in Central America, the eruption wasn’t the first for the locals, who have suffered the wrath of the mountain as recently as July 2015.
Colima, a small state beside Western Mexico, about 155 miles (250km) from Guadalajara, has endured more than 30 periods of eruptions, including several significant explosions in recent years, often covering the town in sheets of ash.

Seismicity
During January 2016, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 70 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a micro earthquake of magnitude 2.5 on January 30, 11:18 PM MST, located 5 miles south southwest of Lake, WY.

January 2016 seismicity was characterized by two earthquake swarms.

1) A small swarm of 16 earthquakes occurred January 30 – 31 (MST) 5 miles south southwest of Lake, WY. The swarm includes the largest earthquake in January (described above).
2) A smaller swarm of 10 earthquakes occurred January 25 – 27. The largest swarm earthquake (magnitude 2.0) occurred January 26, 05:59 AM MST, located 14 miles north northwest of Lake, WY.

Earthquake sequences like these are common and account for roughly 50% of the total seismicity in the Yellowstone region.

Overall, Yellowstone earthquake activity in January was within background levels.

The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

Nevados de Chillan, Chile :

A series of newexplosionswith smallto moderateashemissionsoccurredonthe volcanoduring theweekend.This activity,which has formed anew cratersecond, about 25x30 m wide, located on theslopes ofNorth East o theCraterArrau, was observedby staff ofSERNAGEOMINduring aflyoveron Jan. 30.

According to Chilean scientists, this activity was caused by phreatic explosions (steam) following deep hydrothermal troubles .Are they induced by fresh magma rising ? The temperatures in the crater zones were found to be relatively low (about 120 ° C), which also supports this interpretation.

It islikely that otherexplosionsoccur inthe near future andan exclusion zoneof2 kmaround the craterwascreated.
